About this product
Part Number: ASI120MM-S
The ZWO ASI120MM-S is a super-fast USB 3.0 version of the ASI120MM lunar and planetary imaging camera.
It can deliver up to 254x frames-per-second at reduced resolution or 60x FPS at full 1280X960 resolution!
Peak QE of 75% (better than the ICX618) and no Fixed-Pattern-Noise!
It is also a very capable guide camera. Compared to ICX618 based cameras, like the Imaging Source DMK21AU618, ZWO ASI120MM offers significantly faster frame-rate, slightly higher sensitivity in visual light and more pixels for lunar imaging.
For guiding it offers a solid performer that handles most setups with ease, including most OAG configurations.
The sensor is protected by an anti-reflection clear optical window. If imaging the Moon or planets we recommend fitting a 1.25" UV/IR rejection filter.
The ASI120MM-S’s mono sensor can also be used with specialised UV or methane band filters, as well as infrared passing filters for lunar and planetary imaging (i.e. Baader IR-Pass, Red and Orange visual filters). IR-passing filters cut short wavelengths which prevents atmospheric dispersion softening the image.
Note: The ASI120MM-S has a Micron sensor which might produce Newton Rings when used with solar telescopes. Cameras fitted with Sony sensors are better-suited to this application.
Supplied with a 150-degree accessory lens so you don't even need a telescope to start imaging the stars!
- The lens can be screwed in too far, result in a scratch on the protect window! Please adjust it very slowly! Don’t turn it beyond the focus at infinity!
ASI120 cameras have several reviews at world most popular astronomy magazines. You can read them in PDF documents:
